| int, String int i=12345;
String s= "";
The first method: s=i+ "";
The second method: S=string.valueof (i);
What is the difference between these two methods? Does it work the same? Are they interchangeable under any circumstances? String, int s= "12345";
int i;
The first method: I=integer.parseint (s);
The second method: I=integer.valueof (s). Intvalue ();
What is the difference between these two methods? Does it work the same? Are they interchangeable under any circumstances? The following is the answer:
| first method: s=i+" "; //produces two string objects
The second method: S=string.valueof (i);//Using static methods of the String class, producing only one object the second method: I=integer.valueof (s). Intvalue (); Integer.valueof (s) is equivalent to new Integer (Integer.parseint (s)) and throws an exception, but produces an object more |

String and reshape each other
